Review Quiz-May 16-A

A farmer is trying to optimize the light intensity for photosynthesis in her greenhouse. She knows that different plants have varying light requirements. If she is growing a plant that thrives under high light intensity, which of the following strategies should she consider to enhance photosynthesis effectively?

• Use shading nets to reduce the light intensity.

• Increase the number of artificial lights in the greenhouse.

• Paint the greenhouse glass to reduce light penetration.

• Reduce the operating hours of artificial lighting.

In an experiment to determine the optimal temperature range for germination of wheat seeds, a student sets up several petri dishes with seeds at different temperatures. What would be a strategic approach to determine the temperature range that results in the highest germination rate?

• Place all dishes in the same temperature and observe germination.

• Set each dish at a progressively higher temperature by increments of 5°C.

• Randomly assign temperatures to each dish without tracking.

• Use a control temperature known to be suboptimal and compare others against it.

A study is conducted to find the optimal light intensity for growing tomatoes in a controlled environment. The researcher sets up different sections with varying light intensities. How should she proceed to evaluate the effect of light intensity on tomato growth?

• Measure the height of tomato plants daily.

• Compare the fruit yield of plants under different light intensities.

• Only observe the color of the leaves as an indicator of health.

• Focus solely on the lowest light intensity setup.

To determine the best temperature range for germinating corn seeds, a researcher sets up an experiment with varying temperatures. What method should she use to analyze the results and determine the optimal temperature range?

• Select the temperature where the seeds sprouted first.

• Calculate the average germination rate across all temperatures.

• Identify the temperature range with the highest germination percentage.

• Focus only on the highest and lowest temperature extremes.
